EXPLOSIVE POWER-GENERATOR.

Specification of Letters Patent.

Patented April 23, 1907.

To all whom it may concern:

Be it known that we, HUTOHINSON BEVIER and J ULES J. DURAGE, citizens ofthe United States, residing at Duluth, in the county of St. Louis andState of Minnesota, have invented certain new and useful Improvements inExplosive Power-Generators; and we do hereby declare the following to bea full, clear, and exact des'cri tion of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

Our invention relates to ex losive powergenerators, and has for its oject the provision, in combinationwith a floating vessel or support, ofan improved generator for generating a propelling-gas and for applyingit directly for motive purposes against the water through which thevessel is propelled.

It consists, in combination with a vessel or floating support, of agas-generating and combustion chamber, means for charging said chamberwith hydrocarbon and air, means for igniting said hydrocarbon in thepresence or in mixture with said air, and tubes leading from saidgenerating-chamber to the water in which said vessel is floated.

It also consists of certain other constructions, combinations, andarrangements of parts, as are hereinafter described and claimed.

In the drawings, Figure 1 is a vertical longitudinal section of saidinvention on the line a b of Fig. 2, omitting the containing vessel orsupport. Fig. 2 is a reduced transverse section 0 a vessel, showing arear elevation, partly in vertical transverse section, of saidinvention. Fig. 3 is a reduced detail transverse section of our saidinvention between the lines 0 d and 00 y of Fig. 1. Fig. 4 is a reduceddia rammatic view of a portion of said vesse? and of said invention,showing the arrangement of the propelling and backing tubes of saidinvention. Fig. 5 is a reduced vertical longitudinal section of aportion of said. vessel on the line 8 t of Fig. 2, showing a sideelevation of saidinvention, partly in vertical lon itudinal section.Fig. 6 is a reduced vertica transverse section of a portion of saidinvention on the line 9 h of ig. 1. Fig. 7 is a reduced horizontalsection of said invention on the line 'm n of Fig. 1.

In the drawings, 1, 1,-and 1 are parts of a gas-generating chamber.Throu h said part 1 extends a flue 2, and positione in said part 1 abovesaid flue is a grate 3. Said chamber is provided with a ort 1 foradmitting hydrocarbon into sai chamber and with a ort 1$ for admittinair to said chamber. xtending from sai chamber are two tubes, as 4 and5, communicating with said chamber through ports 4 and 5*, formed in thewalls thereof. Said ports 4 and 5 are governed by any suitable valveconstruction or constructions adapted to open the port 4 and close theport 5, or vice versa, as preferably by a valve 6, pivotally mounted insaid chamber and provided with an outwardlyextending valve-stem 6 andoperating-lever 6 which valve is adapted in one position to close themouth of the port 4 and in another position to open the ort 4 and closethe port 5". Said tube 4 is designed to lead forwardly to and throughthe bow or the side-of thevessel 7 below the Water-line thereof, andsaid tube 5 is designed to lead rearwardly to and through the stern ofthe vessel below the water line thereof. Said chamber is also preferablyprovided with a port 8, normally closed by a safety-valve 8, held downon its seat by a spring 8 adapted to be raised by any excesspower-pressure in said chamber. Said chamber is also preferably providedwith one or more natural-draft airports 9, governed by normally openvalves 9 adapted to be closed by any explosive pressure within saidchamber. Carried by said vessel is a hydrocarbon-reservoir 10, connectedby a tube 11 with the port 1. Said tube 11 is provided with any suitablecurrent-governing valves, as 12, adapted to permit or to out off theflow of hydrocarbon through said tube. by any suitable check-valve 1adapted to be closed by explosive pressure from within said chamber. Alamp or torch 14 is positioned within-a suitable hood or housin 15, withwhich said flue 2 communicates. he oppo site end of said flue preferablycommunicates with a chimney-flue 2"", extending outwardly of saidchamber. Said port 1 by means of a tube 16 and said housing 15 by meansof a tube 1 5 communicate with a fan-chamber 1 7,

preferably at the periphery of said fan-cham- Said port 1 is governedber. Said fan-chamber has journaled therein a fan or blower 18 of anysuitable construction, adapted to be run by any suitable motive meansas,for example, a clockwork mechanism comprising the spring 19, the shaft20, the ti ht ratchet-wheel 21, mounted on said shaft, t 1e loosegear-wheel 22, mounted 011 said shaft, the pawl 23, pivoted to said gear:22 and engaging the teeth of said ratchet 21, the gear 24, meshing withsaid gear 22 and. rigidly fixed on the blower or fan shaft 25. '.Saidfan-chamberis providedwith an inlet port or ports 26, ada ted to admitair to said chamber: Said va vs 12 is provided with avalve-operatingrocker-arm 1 2, adapted to be operated in any suitablemanner by said motor, as by a reciprocating arm 27, ivotally connectedat one end to said roc erarm and at its opposite end connected to aneccentric 28, mounted upon a shaft 29, journaled in suitable supports30. Said shaft 29 is provided at its opposite end with a slidingrotatable gear 31, adapted in operating position to engage a gear 32,mounted upon the shaft 20. The outer end of said shaft 20 is formed intoa winding-stem adapted to en gage the winding-key 33, which ke ispreferably provided with a beveled shou der or collar 33, adapted duringthe winding operation to disengage said gear 31 from said gear 32. Thegear 31 is normally held in operative position by a spring of anysuitable construction, as 34. Below said port 1 which, it may beobserved, is below the port 1, there is formed on the inside wall ofsaid chamber 1 a lip 1, adapted to catch the drip from the port 1 andretain it in such relation to the port 1 that the incoming air throughthe port 1 will scatter and va orize it and mix with it. Said lamp ortore is also connected with said tank by means of a tube 35, andsuitable manually-operated cut-ofl valves, as 36, are mounted in thetubes 11 16, 15, and 35 to permit of the supply of hydrocarbon or blownair being arbitrarily regulated or cut oil from said chamber 1 or fromsaid torch, or both. Said generators, tanks, and powerapplying tubes andgoverning-valves may be single or double or otherwise, as desired, andin the drawings certain portions are shown in duplicate, certain otherportions, as the motor, being single or adapted to use in commen by twogenerators.

In operation the torch is lighted and the flue 2 heated to gas-ignitingheat. The motor is then statred, tnus admitting to the chamber 1 acharge of hydrocarbon and simultaneously a forced draft of air in properproportions to make an explosive mixture, which is thereupon ignited 'orexploded by the heated flue 2. The expanding gas seeking to escapethrough the tube 4* or 5 as the case may be, pushes directly against thewater, thus backing the vessel or propelling it ahead, as the case maybe. After the chamber 1 is thoroughly heated and the grate 3 isthoroughly heated by explosions of gas it is believed that said torchmaybe extinguished without stopping the engine. The volume of air blowninto said chamber and the amount of hydrocarbon admitted thereto may bereadily regulated by means of the said manually-o erated valves 36. Itwill be observed that tlie generators contain no power-pistons and thatthey are alwa sin direct communication through one or t e other of thetubes 4 or 5 with the water surrounding the vessel. We do not desire,however, to be restricted to the especial form of motor, as said clockmechanism, shown or described or to the particular forms of valves, itbeing evident that various minor or convenient modifications may be madein said constructlons without departing from the spirit or scope of ourinvention.

Having now described our invention, what we claim, and desire to secureby Letters Patent, is

combination with a vessel or floating support, of a gas-generating andcombustion chamber adapted to communicate at all times directly with thewater surrounding said vessel, means including a clockwork mechanism,and blower, adapted to introduce a charge of air into saidgeneratingchamber, means for separately introducing a charge ofhydrocarbon into said chamber, and means adapted to ignite said chargesin mingled condition in said chamber.
